Does anyone else have this? It's like a "false" gout, an arthritus where calcium pyrophosphate crystals get into the knee joint and sometime are embedded in the cartilage. Hurts like crap. I've had the knee drained 4 times with cortisone injection as well over the last 6 weeks. Ortho doc wants to do Arthroscopic surgery to clean it out. They say it's not really treatable but manageable for some, more degenerative for others. Anybody know anything about this? I'm pushing 50.
